D850 D1650 D850, D1650 Multichannel Digital Power Amplifiers Installation Manual
SAFETY INSTRUCTIONS 6. Cleaning - The appliance should be cleaned only as recommended by the manufacturer. From time to time you should wipe off the front and side panels and the cabinet with a soft cloth. Do not use rough material, thinners, alcohol or other chemical solvents or cloths since this may damage the finish or remove the panel lettering. WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS APPLIANCE TO RAIN OR MOISTURE.

BACK PANEL FEATURES Power/Standby LED AC Input / Voltage Switch This LED lights red when any zone is active or the amplifier is in standby mode. When a zone is powered on, the corresponding LED lights blue. When a zone is OFF, the LED is off (standby mode). If a short circuit happens on the speaker outputs, the LED will blink fast red and blue. Voltage is set with a selectable switch for 115V or 230V operation.
TYPICAL SYSTEM CONFIGURATION Both the D850 and the D1650 can be configured as the main amplifier for an audio distribution system or home theater system. When used with an audio distribution preamp, each zone can independently drive one of several different sources by using each zone’s individual line audio inputs, or a pair of zones can be Bridge to create a higher powered zone. When the D1650 is used as a home theater amplifier, up to a 7.1 system can be supported.
BRIDGE MODE OPERATION When the amplifier is in Bridge mode operation, a single channel (the left) is used to produce a high power mono output. Use one channel pair to amplify the left channel by connecting the left audio signal to the L input of a channel pair, setting the Stereo/Bridge switch to "Bridge" and connecting the speaker as indicated below.
USING SIGNAL SENSING D850 and D1650 amplifiers have a signal sensing feature which will allow the amp to turn on automatically when a signal from the source is “sensed”. This is useful if the source used with the D850 or D1650 amplifier does not have a 12v trigger option. There are many factors affecting the signal sensing of the D-series amplifiers, and you can see a few recommendations and common scenarios listed below to help set the levels in the system to best optimize the signal sensing feature.

TROUBLESHOOTING Signal Sensing Problems The D-series amp zone does not turn on: • Check the input signal path • Check the audio cable connections between the source and the amp • If the source is a variable signal, make sure it is turned up The D-series amp zone turns on, but not consistently • Check the input signal level. It may need to be turned up • Check the amp gain levels.
